OK but, that is not important here. If the machine which is running the 
apache webserver read the index.php, it runs in the local memory. Then 
when th file_exists() is executed, the mounted partition, if any, is 
requested another time.

Does the VFS use the « Principle of Locality » to cache remote file 
access too ?

You didn't say is a local hard drive. :-)

I'm remembering that php also has cache stat file system, See 
clearstatcache().

See also, http://www.php.net/manual/en/function.file-exists.php
discussion, about when it fails.

Hope that helps, I'm a sysadmin, too. ;-)
